Engineering technologies for fluid chemical hydrogen storage system

An efficient gas/liquid separator (GLS) was developed for separating hydrogen gas from spent liquid organic and inorganic hydrogen carriers onboard light-duty vehicles. The results show that the capacity of the GLS is sufficient for an 80 kWe PEM fuel cell, as used in light-duty vehicle applications. A discrepancy was observed between the calculated droplet size distribution at the outlet of the GLS and the experimental results. This was explained by film formation and breakup inside the vortex finder when the GLS was operated at flow rates that exceeded its critical gas velocity. (C) 2015 United Technologies Corporation.
